LLM/MLLM Algorithm Engineer - Global E-Commerce

About the Team The team focuses on the development of large models in NLP, CV, and multimodal domains. The team aims to establish state-of-the-art (SOTA) models while delving deeply into these areas to optimize algorithms for e-commerce data, thereby enhancing business outcomes. By refining algorithms and collaborating with business operations, the team strives to govern the quality and ecosystem of ByteDance's e-commerce products comprehensively. This includes addressing issues such as risks, violations, and low-quality content, while also fostering the e-commerce ecosystem. The ultimate goal is to maximize platform governance efficiency and effectiveness.

Job Responsibilities - Large language Model Algorithm Development: Build domain-specific large language models (LLM/MLLM) for e-commerce, integrating domain knowledge to rapidly apply models to business scenarios. - E-commerce Governance Optimization: Understand e-commerce governance scenarios deeply to improve merchant/product/video/live-stream/IPR governance through algorithm optimization. Develop state-of-the-art intelligent review systems capable of “knowing why to reject” decisions. - Model Enhancement: Handle tasks like data construction, foundational model enhancement, instruction fine-tuning, chain-of-thought (CoT) , and parameter-efficient fine-tuning (PEFT) to achieve optimal model performance in the e-commerce domain. - Problem Solving for Governance Applications: Address challenges such as long text/sequence modeling, few-shot learning, content moderation, violation detection, and policy recommendation using large models and multimodal approaches. - Model Development and Optimization: Research and optimize e-commerce-specific NLP and multimodal large models to improve multilingual, multi-task, and multi-modal algorithm performance across various e-commerce scenarios.
